  3. Analyst is using INISTATE to import S, EPPL and EPEL, but does not get correct results. He uses UPGEOM to update the geometry shape and fixes all the nodes to check what was read in, but does not get the same stresses that were initially read in. Reactions are off too. What is wrong?

      To get the same stress state and reactions, you need to read in elastic strain, plastic strain, equivalent plastic strain and plastic work, but do not read in the stress. If you do read in the stress, then you should not read in the elastic strain, but you still need to read in the plastic strain components listed above, because the plasticity is not fully represented otherwise.
